Possible to route ETR to a TIM1 channel
I have a product using a STM32H745ZIT that has an input signal connected to TIM1 ETR and in the normal case, an edge on the ETR using slave mode trigger results in a one pulse pwm output a set time later driven on TIM1 CH1 and TIM1 CH2. A new use case came up where it is desirable to duplicate TIM1 ETR onto one of the TIM1 CH pins that duplicates both the edges and pulse length of the ETR signal with no time shift.
Looking over the reference manual it isn't obvious that I can do this, maybe using trigger out or break there is a way. Is there anybody knowledgeable with the working of TIM1 and ETR that can suggest where to look?
